Beaver Ball silencers are an effective and easy to install bow string silencer. Just seperate your string with your finger nail and tuck one end of the silencer through. Then wrap the remaining silencer around the string and then tuck the other end in the string again. Push the ball together to form a good looking ball.
Naturally water resistant and quiet.
I haven't seen the beaver since I put his balls on my bow string. The Beaver Ball Silencers work really well. Very easy to install and the string twang is much quieter. Very satisfied and would recommend.
